Signature fitness jammer lever arms $45 @ woot. Looks to be their older style with the 5/8" pin only. I just got these on Amazon for $80 and I thought that was a good deal so this is a no brainer. Be advised - the articulation of the arms can cause the weights to fall off so use collars! Unfortunately, signature fitness used axel sized bars so your 2" won't work on these. The ones I just got (same style) mine came with spring collars that fit so as long as everything is in the box, you're good to go. An old school screw collar also would work on this if necessary.
Another issue is that they don't have pins to limit the range of motion. That's good to give you flexibility, bad because there are no stops. Use webbing, chain or a spotter arm/weight horn to hold them in place if needed.
Here's a great video of exercises you can do

This exact pair? Because they have a full 360° rotation, not just up and down like others. They're like a shoulder joint
I think part of the problem is the 360 rotation, rather than just a levered up and down. The 360 rotation makes them pivot all over the place, rather than a controlled and smooth up/down movement. Also, they would rattle around on the rack with lots of play, I guess unless you have a 3x3 and they fit tight without slack between the joint and the rack. Otherwise, the joint will rattle around. I think the U-Joint is a bad idea. Also, the weighted end would drop to the floor, which wouldn't work for anything except deadlifts or rows where you wanted the weight to rest on the floor. If they were up/down only, you could use spotter arms or chains to support them for things like bench press or squats. But with the U-Joint they would flop all over the place and drop off the spotter arms or swing around on the chains.
I almost feel like this is a "Solution looking for a Problem" kind of thing. Why not just use a barbell to do all the exercises? I really want to like the product, but also trying to only buy products that add significant value for the space they take up in my limited garage gym. These seem like they would be two large bars propped up against the wall and seldom used.

I watched that video I linked above and got excited about all of the possibilities. At $45 I went for it. I definitely would not have paid hundreds for a set.
And yes, the extra articulation is good and bad. They do not have a pin that can limit the range of motion so getting them up and off of the rack as a starting point can be a problem but it can mimic the Hammer Strength machines better because they are not restricted to the one plane of motion. Goods and bads but that's why I was only willing to go for it at $45

I might still bite for 45 bucks.
